Return residuals of an nlrq object
Set algorithmic parameters for nlrq (nonlinear quantile regression function)
# S3 method for nlrq residuals(object, type = c("response", "rho"), ...)
an `nlrq' object as returned by function `nlrq'
the type of residuals to return: "response" is the distance between observed and predicted values; "rho" is the weighted distance used to calculate the objective function in the minimisation algorithm as tau * pmax(resid, 0) + (1 - tau) * pmin(resid, 0), where resid are the simple residuals as above (with type="response").
